Teachers can modify problem sets and the individual questions in the
problem sets or make their own problem sets. All teachers have access
to three types of Assistments:
- Those they created themselves
- Those that are endorsed by the Assistment system
- Those shared with them by another teacher
The system allows teachers to create many different kinds of problem
sets from linear order to randomized. Teachers can browse available
problem sets and then assign whatever subsets or regroupings of these
problem sets they would like.
